Description

  The present invention relates to a slitter device that rewinds a wide winding, cuts it into a plurality of narrow windings, winds each narrow winding around a plurality of core shafts, and creates a plurality of small windings.

A device called a slitter that unwinds a wide winding, cuts it into a plurality of narrow windings with a leather blade, etc., winds each narrow winding around a plurality of core shafts (paper windings), and creates a plurality of small windings (For example, refer to Patent Document 1).
The slitter device according to Japanese Utility Model Publication No. 7-56274 is stopped when the narrow winding is wound up to a predetermined diameter, and after the winding end of each small winding is cut, from the holding shaft that is moved in the coupled state from the device main body. The small winding is removed, a new core shaft is mounted at a predetermined position of the holding shaft, and a part of the cut end is joined to the new core shaft with tape or the like to prepare for a new winding operation. This series of work is called rewinding work.

  Since the slitter device is a device that generates a plurality of small windings with a small winding diameter from a wide winding with a large winding diameter, rewinding work frequently occurs, and the cutting operation speed of the slitter device is increased. However, there is a problem that the production efficiency of the slitter device is lowered by the rewinding work.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to shorten the stop time due to the rewinding work of the slitter device.

  In order to solve the above-mentioned problems, the first aspect of the present invention is to rewind a wide winding, cut it into a plurality of narrow windings, wind each narrow winding around a plurality of core shafts, In a slitter device for producing a plurality of small windings, a second holding shaft set including a plurality of first holding shafts holding the core shaft and a plurality of second holding shafts holding the core shaft is provided. The first holding shaft is connected to one end of the first holding shaft by the first connecting portion of the slitter device, and the first connecting portion is used as an axis. The second connecting portion of the slitter device is rotated in the horizontal direction by the first rotating mechanism, and the second holding shaft has one end of the second holding shaft at a position opposite to the first holding shaft. And is rotated in the opposite direction to the first holding shaft by the second rotating mechanism having the second connecting portion as an axis. It is those that you have configured.

  According to a second aspect of the present invention, in the slitter device according to the first aspect described above, the first holding shaft group and the second holding shaft group are wound with a narrow-width winding wound. The rewinding work, which is the preparation for the next winding work, is shared by each holding shaft group, so that it can be executed simultaneously.

  By connecting the holding shaft sets of a plurality of holding shafts that take up the small windings of the slitter device, respectively, with different ends from the other holding shaft sets, and rotating the holding shaft in the horizontal direction around the connecting portion, By enabling the rewinding work in the holding shaft assembly, it is possible to shorten the time for the rewinding work and to operate the winding work, that is, the slitter device, in the other holding shaft.

  Hereinafter, the present invention will be described based on embodiments shown in the drawings. FIG. 1 is a perspective view of the slitter device of the present invention. A slitter device having two sets of holding shafts each including two holding shafts will be described.

  The slitter device has a holding shaft assembly in which two holding shafts are paired up and down by a rotation mechanism having two connecting portions of left and right device frames as shafts and a drive source with a clutch of the opposite device frame. Two sets are provided.

  The first holding shaft assembly 1 is separated from the device frame at the drive sources 2 and 3 of the right-side device frame, and is horizontally turned clockwise by the rotation mechanisms 4 and 5 with the connecting portion of the left-side device frame as a fulcrum. Two holding shafts that rotate in the direction are provided.

  The second holding shaft group 6 is separated from the device frame at the drive sources 7 and 8 of the left-side device frame, opposite to the first holding shaft set 1, and the connecting portion of the right-side device frame is a fulcrum. As an example, a holding shaft that rotates counterclockwise in the horizontal direction is provided by the rotation mechanisms 9 and 10.

  As shown in FIG. 1, the first holding shaft assembly 1 and the second holding shaft assembly 6 are connected to each other at connecting portions of different device frames. It moves (for example, moves to a position that forms 90 ° with respect to the apparatus).

  Hereinafter, the operation and operation of the slitter device of the present invention will be described. As in the example shown in FIG. 1, the second holding shaft 1 is driven while the first holding shaft assembly 1 is driven by the drive sources 2 and 3 to perform the winding operation of the cut narrow winding. The shaft set 6 is rotated in the horizontal direction by the rotation mechanisms 9 and 10 and moved to a predetermined position, and a new core shaft is attached to the predetermined position.

  In the two holding shafts of the first holding shaft assembly 1, when the small winding to be wound reaches a predetermined winding diameter, the slitter device is temporarily stopped and the winding end is cut.

  While holding the small winding, the first holding shaft assembly 1 is separated from the device frame in the drive sources 2 and 3, and the first holding shaft assembly 1 is moved to the left side of the slitter device by the rotation mechanisms 4 and 5. Moving.

  Immediately after moving the first holding shaft assembly 1, the second holding shaft assembly 6 with the new core shaft attached at a predetermined position is rotated in the horizontal direction by the rotating mechanisms 9, 10, and the drive source 7, 8 is connected to a slitter device.

  A part of the cut end is joined to a new core shaft attached to the second holding shaft assembly 6 with a tape or the like, the operation is resumed, and the winding operation is performed in the second holding shaft assembly 6.

  After the operation is resumed by the second holding shaft assembly 6, a plurality of small windings held on the first holding shaft assembly 1 that has been moved are removed, and a new core for the next winding operation is removed. The shaft is attached to a predetermined position of the holding shaft and waits.

  When the winding operation of the second holding shaft assembly 6 is completed, it is replaced with the first holding shaft assembly 1 again. Repeat this.

  As a result, during the operation of the slitter device, it is possible to perform a rewinding operation for the next small roll in advance, and the stop time of the slitter device can be shortened.

It is a perspective view of the slitter apparatus of this invention.
